Newest firstSeveral studies show that neurosteroids currently play a significant role in autism spectrum disorders (ASD). However, the pathway of neurosteroid synthesis involved in ASD remains unclear. This study aimed to investigate the crosstalk between autism and neurosteroids, focusing on the mechanism of allopregnanolone production. We used the BTBR T+ tf/J (BTBR) mouse, a well-established animal model of ASD that exhibi…
Open article record in new tab ↗Background Cannabis constituents, including Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), show distinct pharmacological profiles with therapeutic relevance for neurological and psychiatric conditions. THC exerts euphoric effects primarily via CB1 receptor activation, while CBD displays non-euphoric properties affecting various pathways. Aims This study evaluated the effects of THC, CBD, and their combinatio…
Synthetic cannabinoids (SC) target the human cannabinoid receptor 1 (hCB1) and are extensively metabolized, but the metabolite activity on the hCB1 receptor after a SC intake is largely unknown. In this study we compared the in vitro hCB1 receptor activity of 26 metabolites of the synthetic cannabinoid receptor agonists (SCRA) JWH-018, AM-2201, THJ-018 and THJ-2201 as a model system for SC metabolite activity to e…
Hemp products [cannabis with ≤0.3% Δ9-tetrahydrocannabinol (Δ9-THC)] are federally legal, but few controlled experiments have explored drug test results, pharmacokinetics, or pharmacodynamics. Healthy adults (n = 60) self-administered 1.5 mL medium-chain triglyceride (MCT) oil containing 100 mg cannabidiol (CBD) and either 0, 0.5, 1, 2, 2.8, or 3.7 mg Δ9-THC (n = 10 per group). The study included an 8-hour acute d…
Introduction Cannabidiol has been shown to exert significant anti-inflammatory effects and has demonstrated efficacy in murine models of autoimmune myocarditis, pericarditis, and heart failure. The ARCHER Study assessed whether a pharmaceutically produced cannabidiol formulation showed beneficial effects on cardiac magnetic resonance (CMR) endpoints known to predict prognosis in this patient population. Methods In…
Rationale Exposure to traumatic events can lead to alterations in social and anxiety-related behaviors. Emerging evidence suggests that peripheral host-defense processes are implicated in the expression of stress-induced behavioral responses and may be targeted to mitigate the negative sequalae of stress exposure. Objectives In this study, we used the peripherally restricted FAAH inhibitor URB937 to investigate th…
Background Cannabidiol (CBD) has numerous therapeutic properties, and is used to treat neurological conditions, such as neuroinflammation. However, the optimal dose of CBD to penetrate the brain requires further investigation. The primary aim of this study was to use a mouse model and the intrabuccal route for CBD administration to determine the optimal dose at which CBD can penetrate the brain. The secondary aim…
Open article record in new tab ↗Pharmacotherapy for major anxiety disorders continues to present dangerous side effects, complicating precise treatment choices for each patient. In this context, β-caryophyllene (BCP), a selective agonist of the cannabinoid type II receptor (CB2R), is recognized as a safe immunomodulatory drug. CB2R has recently been identified in glutamatergic and dopaminergic neurons, supporting its potential as a pharmacothera…
Study objectives Current treatments for obstructive sleep apnea (OSA) are ineffective or not tolerated in a proportion of patients. Other therapeutic options are needed and pharmaceuticals may provide an alternative. This randomized, double-blind, placebo-controlled, crossover study examined the effect of a combination of acetazolamide and dronabinol (IHL-42X) at low, medium, and high doses on OSA severity. Method…
Background The use of psychedelics is currently increasing in the United States. Awareness of clinical trials investigating the therapeutic applications of psychedelics may result in a record number of people who use psychedelics for the first-time. This study aimed to develop a harm-reduction resource to facilitate safe and successful psychedelic experiences outside of regulated clinical and research settings. We…
Background Recent preclinical studies have shown sex-dependent antidepressant-like responses of cannabidiol in adolescence, which were dependent on biological sex, early-life stress, and dose. In particular, cannabidiol (10 mg/kg) induced acute and sustained antidepressant-like responses in adolescent male rats, while it lacked efficacy in females. This follow-up study aimed at further characterizing cannabidiol's…
Open article record in new tab ↗Tau is a neuronal protein that confers stability to microtubules; however, its hyperphosphorylation and accumulation can lead to an impairment of protein degradation pathways, such as autophagy. Autophagy is a lysosomal catabolic process responsible for degrading cytosolic components, being essential for cellular homeostasis and survival. In this context, autophagy modulation has been postulated as a possible ther…
Oxidative byproducts of cannabidiol (CBD) are known to be cytotoxic. However, CBD susceptibility to oxidation and resulting toxicity dissolved in two common solvents, ethanol (EtOH) and dimethyl sulfoxide (DMSO), is seldom discussed. Furthermore, CBD products contain a wide range of concentrations, making it challenging to link general health risks associated with CBD cytotoxicity. Here, we report on the effect of…
The cannabinoid receptor type 2 (CB2R) is overexpressed under pathological conditions. Positron emission tomography is a noninvasive imaging technique for diagnosing disease states, but requires radiotracers with high affinity and selectivity towards CB2R. Currently, there is no suitable candidate routinely used in the clinics. The naphthyridinone scaffold, a promising core structure, has been modified in the past…
Open article record in new tab ↗Context As a naturally occurring terpenoid found in Cannabis sativa L. (Cannabaceae), cannabidiol (CBD) has gained public and industry interest for the purposes of personal well-being as a foodstuff and pharmaceutical. Despite a number of publications on CBD toxicology, many have significant limitations, especially those relating to genotoxicity. These include poor characterization of the CBD extract and/or lack r…
Open article record in new tab ↗Emergency department visits due to cannabinoid-induced toxicity, including acute cannabinoid intoxication (ACI) have increased worldwide as more states have liberalized cannabis policy. ACI symptoms include anxiety, panic attacks, tachycardia, and psychosis, primarily mediated through cannabinoid type 1 receptor (CB1) agonism by Δ9-tetrahydrocannabinol (THC). This phase II randomized, double-blind, placebo-control…
Delta-9-Tetrahydrocannabivarin (THCV), a naturally occurring cannabinoid and structural analog of THC, exhibits a dual pharmacological profile as a CB1 receptor agonist/antagonist and a partial CB2 agonist. This study evaluated the effects of THCV in a THC discrimination model in rats. Male Sprague-Dawley rats (n = 16, 300-340 g, PND60) were trained under a fixed ratio 20 (FR20) schedule to discriminate THC (3 mg/…
The increasing use of cannabis for medicinal and recreational purposes highlights the need to understand its psychoactive effects. Δ-9-tetrahydrocannabinol (THC), the primary psychoactive cannabinoid, is responsible for feeling high and reduced alertness after cannabis use. This study aimed to develop and verify physiologically based pharmacokinetic-pharmacodynamic (PBPK-PD) models to quantify the effects of THC a…
Open article record in new tab ↗Rationale Schedule-induced drinking (SID) reproduces an excessive and repetitive behavioural pattern that has led to propose this procedure as an animal model to study compulsive behaviours. Although it is known that cannabis can cause several adverse effects, in recent years there has been great interest in the medical application of cannabis derivatives for obsessive-compulsive related disorders. Objectives The…
Open article record in new tab ↗Natural non-psychoactive cannabinoids such as cannabigerol (CBG), cannabidiol (CBD), cannabichromene (CBC), cannabidivarin (CBDV), and cannabinol (CBN) are increasingly consumed as constituents of dietary products because of the health benefits claims. Cannabinoids may reduce certain types of pain, nausea, and anxiety. Anti-inflammatory and even anti-carcinogenic properties have been discussed. However, there are…
